Reduce stack usage for recursive traverse_visitbp()
...
Due to limited stack space recursive functions are frowned upon in
the Linux kernel. However, they often are the most elegant solution
to a problem. The following code preserves the recursive function
traverse_visitbp() but moves the local variables AND function
arguments to the heap to minimize the stack frame size. Enough
space is initially allocated on the stack for 20 levels of recursion.
This change does ugly-up-the-code but it reduces the worst case
usage from roughly 4160 bytes to 960 bytes on x86_64 archs.

Linux bcopy() requires word aligned memory, use memcpy()
...
Much to my surprise bcopy() under Linux appears to copy the data in
word sized chunks. It does the right thing but if you buffer is not
a multiple of the word size you will be reading past the end of your
buffer. Or at least that is what valgrind is reporting. We should
be using mempcy() anyway on Linux so replace bcopy() with memcpy()
to resolve the issue.

There are cases where under Linux it is not safe to sleep in

allow a sleep here. The impact of this should be minimal.

Add fix-stack-dsl_deleg_get topic branch
...
Reduce stack usage in dsl_deleg_get, gcc flagged it as consuming a
whopping 1040 bytes or potentially 1/4 of a 4K stack. This patch
moves all the large structures and buffer off the stack and on to
the heap. This includes 2 zap_cursor_t structs each 52 bytes in
size, 2 zap_attribute_t structs each 280 bytes in size, and 1
256 byte char array. The total saves on the stack is 880 bytes
after you account for the 5 new pointers added.
Also the source buffer length has been increased from MAXNAMELEN
to MAXNAMELEN+strlen(MOS_DIR_NAME)+1 as described by the comment in
dsl_dir_name(). A buffer overrun may have been possible with the
slightly smaller buffer.

Add linux-sha2 topic branch for portability
...
The upstream ZFS code has correctly moved to a faster native sha2
implementation. Unfortunately, under Linux that's going to be a little
problematic so we revert the code to the more portable version contained
in earlier ZFS releases. Using the native sha2 implementation in Linux
is possible but the API is slightly different in kernel version user
space depending on which libraries are used. Ideally, we need a fast
implementation of SHA256 which builds as part of ZFS this shouldn't be
that hard to do but it will take some effort.

Reduce kernel stack usage by lzjb_compress() by moving uint16 array
off the stack and on to the heap. The exact performance implications
of this I have not measured but we absolutely need to keep stack
usage to a minimum. If/when this becomes and issue we optimize.

Add fix-metaslab topic branch
...
If your only going to allow one allocator to be used and it is defined
at compile time there is no point including the others in the build.
This patch could/should be refined for Linux to make the metaslab
configurable at run time. That might be a bit tricky however since
you would need to quiese all IO. Short of that making it configurable
as a module load option would be a reasonable compromise.

and can never be used as a local variable in a function. Simply
replace all usage of 'current' with 'curr' in this function.

Updated fix to detect if we are in an interrupt and only sleep if it

Update linux-kernel-disk ZVOL implementation
...
The ZVOL interfaces changed significantly with the latest update. I've
updated the Linux version of the code to handle this and it looks like
the net result has been a simpler implementation which is good! Plus,
I'm relatively sure the ZIL integration is right this time although it
needs some serious crash testing to verify that.
Also minor additions to vdev_disk for .hold and .rele callbacks.
Currently, they do nothing and I may be able to simply stub them out
with NULLs for Linux since opening the device in Linux should have
much the same effort. More investigation is needed though since
the ZFS interface may make some demands here I'm overlooking.

Update linux-zpios to use updated DMU API
...
The DMU API has been modified to remove the dmu_objset_open, and
dmu_objset_close functions. Now you must explicitly *_create an
objset, then *_own it, *_disown it when not in use, and *_destroy
it when your through. All and all I like the API much better.
Additionally, while I was here I moved the zpios_cmd_t off the
stack because previous analysis showed it was very stack heavy.
